BOARDING-MACHINE.

Application filed. March 23, 1915, Serial No. 16,511.

To all whom it may concern:

Be it known that I, CARL A. RAUSGH, of 13 Roscherstrasse, Leipzig-Gohlis, in the Kingdom of Saxony, German Empire, have invented certain new and useful Improvements in Boarding-Machines, of which the following is a specification.

My invention relates to boarding machines used in the manufacture of leather, and the object of my invention is to provide boarding members difierent from the board ng plates hitherto used, the use of said improved boarding members presenting a decided advantage in the art of boardlng leather.

In the boarding machines hitherto used the hide was introduced in folded-up condition between two plates having a reciproeating motion in opposite directions and therefore rolling the doubled-up hide to and fro between them. Inthe preferred form of machines of this type the plates are arranged in substantially vertical position and on account of the hide introduced between them being also substantially in a vertical position the friction between the free parts of the hide pending freely down was considerably less than with the horizontal treatment formerly employed.

According to my invention at least one of the flat boarding plates is replaced by a rotatable boarding member having a curved, preferably a cylindrical working surface. In the case of one curved boarding member and one flat boarding plate being combined, the axis of rotation of the'curved member is substantially parallel to the plate, and in the case of two curved boarding members being employed, their axes are substantially parallel and at substantially the same level. In all cases the two halves of the hide introduced between the members pend clownward substantially vertically, as in the older machines. If one curved member such as a member having the shape of a cylindrical segment is employed in combination with a fiat member or plate, the operations of introducing and of removing the hide are rendered much easier. The same is true of the combination of two curved members, either cylindrical segments or true cylinders, as will be explained in the description hereinafter given.

Specification of Letters Patent.

Renewed October 16, 1918. Serial No. 258.394.

In the drawings annexed to this speciiication Figures 1 and 2 are diagrammatic side views of one modification of the invention, Fig. 1 showing the boarding members in working position, while Fig. 2 shows the position of parts facilitating the removal of the hide.

Fig. 3 is a diagrammatic side View of another modification.

Figs. c and 5 are views partly in section of operative machines employing respectively the boarding members of Figs. 1 and 2 and Fig. 3. i

In the modification shown in Fig. 1 2' is a fiat boarding plate linked to a reciprocating rod g, z" is a curved boarding member hav ing a working surface shaped like a cylindrical segment and oscillating about a horizontal axle 1, an oscillatory movement being imparted to it by a connecting rod 2 pivoted to an arm 3 of the member. The plate 2' and segment 2" move to and fro in opposite directions. A plate 8 inserted in and carrying the folded-up hide is adapted to be introduced from below between the two boarding members and to be tilted sidewise away from the plate 2'. lVhen it is desired to remove the hide from between the boarding members, the segment 2" 'is caused to swing into an almost vertical position, while the plate 2' is shifted downward, thus leaving the plate 3 carrying the hide to be tilted to the left (Fig. 2) and to allow the hide to fall oil or to be removed by hand.

In the modification shown in Fig. 3 two curved boarding members i and i are combined, both being rotatably fastened to parallel horizontal axles Z and connected to rods 2 adapted to reciprocate in a substantially vertical direction and to cause the segments to oscillate in opposite directions, thereby pulling the hide introduced between them on a plate 8 to travel over the upper edge of said plate.

Referring to Fig. at in which mechanism is shown for actuating the boarding members shown in Figs. 1 and 2, 64 represents a frame in which is mounted a vertically reciprocable sliding block b, which in turn carries a stem (Z of a disk on which is mounted the boarding plate 2'. A threaded spindle c is provided with a hand wheel whereby the stem (Z may be advanced .or retracted for diminishing or increasing as desired, the distance between the boarding plate 11 and the co-acting boarding plate 2". The plate 2" is' carried on the curved surface of a sector pivoted on the pin'l, the pin 1 being supported.

by the frame a. Between the, boarding plates 2', '11, is shown the hide supporting eating the sliding block b and with it the boarding plate 2' comprises a belt pulley 0 carried by the axle 7), eccentric 9, link r and'connecting rod 9. The means for oscillating the sector 'and'boarding plate 71 comprises the aforesaid beltpulley 0, eccentric 15, the lever u pivoted at Z, connecting rod 2 and lever 3. When in operative position, the sector is locked with the lever 3 by means of the detent or pawl 3 pivoted on the pin :0 carriedby the sector. The rear end of the detent- 31 is downwardly displaceable, a rod or handle 2 extending across the breadth of the machine, being provided for thispurpose; lVhen it is desired to dispose a hide on theplate s, or remove one therefrom, the handle a is pressed downwardly. thereby breaking the. locking engagement between the sector and lever 3, and the sector and plate 8 are then thrown into the positions shown in broken line.

In Fig, 5, I have shown a mechanism for actuating the boarding plates illustrated in Fig. 3. Except as now pointed out, the construction and operation of the various parts are the, same as described with reference to Fig. 4. The curved boarding plate 2', which here takes the place of the flat boarding plate 2' shown in Figs. 1, 2 and l, is pivoted on the pin 1, carried .by the slide f,

which in turn is carried by the housing 9 rigidly secured to the frame a. The means for oscillating the boarding plates 71 and 2' past each other in opposite directions comprises belt. pulley 0, eccentric p, arm 9 rigidly carried by the axle Z, lever 1", connecting rods-22 and levers 3-3.

The lever 3 at the left is locked withits sector in the manner described with reference to Fig. 4. It is preferred to form the lever 3 at the right as a rigid arm or integral member of its sector.

I claim 1. In a boarding machine, in combination, two-boarding members, the working faces of'said members facing each other, at least one of said members having a curved working face, means for introducinga hide vertically between said'members and means for imparting to the working faces of said members an up and down movement in opposite directions.

2'. Ina boardingmachine, in combination, two boarding members, tl1e working faces of 'saidmembers facing each other, at least one. of said members having a curved'working face andbeing rotatably mounted in said machine whereby it'may be movediinto and out of operative position, means for introducing ahide vertically: between said members and means for, imparting to the working faces ofisaidimembers an up and down movement'in opposite directions.

3. In a boarding machine, in combination, two boarding members having curved working surfaces facing each other, means for introducing alhide vertically between said members and means for imparting to the curved working. surfaces oscillatory opposite movements in the1r arcuate paths.

4:. In a boarding machine, in combination, two boarding members, the working faces of said members facingeach other, atleast one of said members having a curved working face, a support for introducing a hide vertically between said vmembers and permitting the free ends of the hideto hangdownward on both sides of'it, and means for impart: ing to the working faces offsaid'members an up and down movement in opposite directions.

In testimony whereof I-affixmy signature in presence of two witnesses.
